Or maybe people will hear this and google Hubbell and Chelsea and look at the pics. I think the Clintons are still using the 1994 playbook and have not adapted much to the fact that everybody has access to the internet pretty much everywhere now. I do not see this hurting Trump any.
It's not going to hurt Trump, because it's not Trump who's saying it or even somebody currently with the campaign, just some wannabe hanger-on.
I can't think this is going to motivate people to "discover" anything about Hubbell and Clinton because everybody who cares about it has already heard the rumor a quarter century ago.
It's a pretty stupid rumor. You've only got to google "Virginia Clinton Kelley" to get an idea of where Chelsea's looks came from. And anybody who believes both the Hubbell-Chelsea story and the Hillary lesbian rumors probably isn't playing with a full deck.
